Abstract

Module de transmission d'une radio numérique programmable, possédant un sous-module numérique qui reçoit un train de bits et produit un signal de fréquence intermédiaire modulé, et un sous-module analogique qui reçoit le signal de fréquence intermédiaire modulé et convertit ledit signal en une fréquence correspondant à un type spécifique de fonction radio. Ledit sous-module numérique comporte (a) un processeur de jeux d'instructions séquentiel/parallèle pour le traitement et la commande des signaux, (b) une unité de format reconfigurable pour produire des signaux de sortie destinés à transmettre différents types de fonctions radio, et (c) un modulateur qui reçoit les signaux de sortie de l'unité de format reconfigurable et produit le signal d'oscillation modulé. Le sous-module analogique comporte (a) un oscillateur local accordable qui produit un signal d'oscillation locale accordable, (b) des oscillateurs locaux fixes qui produisent des signaux d'oscillation locale fixes et (c) une unité de mixage qui reçoit le signal de fréquence intermédiaire modulé, le signal d'oscillation locale accordable et les signaux d'oscillation locale fixes, mélange sélectivement les signaux d'oscillation locale modulés avec le signal d'oscillation modulé pour produire des signaux de fréquence intermédiaire non finaux, et mélange un signal de fréquence intermédiaire non final avec le signal d'oscillation locale accordable pour produire un signal converti final destiné à être transmis à la fréquence correspondant au type spécifique de fonction radio.
